1.1.2. 6.144 Gbps CPRI Support Capability in GT Devices

You can configure Cyclone® V GT devices to support 6.144 Gbps for CPRI protocol only. The Cyclone® V GT device supports up to three full duplex channels that are compliant to the 6.144 Gbps CPRI protocol for every two transceiver banks. The transceivers are grouped in transceiver banks of three channels.

Altera recommends that you increase the VCCE_GXBL and VCCL_GXBL to a nominal value of 1.2 V in order to be compliant to the 6.144Gbps CPRI protocol. The reference clock frequency for the 6.144 Gbps CPRI channel must be ≥ 307.2 MHz.
